The stamp, priced at 60 cents, will be available nationwide that day. The price includes the first-class single-piece postage rate in effect at the time of purchase plus an amount to fund Alzheimer’s research. By law, revenue from sales of the Alzheimer’s semipostal — minus the postage paid and the reimbursement of reasonable costs incurred by the Postal Service — will be distributed to the National Institutes of Health, which is part of the U.S. Department of Health and Human Services.

If the stamp looks familiar, you’re correct. The artwork is an illustration that first appeared on the 2008 42-cent Alzheimer’s Awareness stamp. It shows an older woman in profile with a caring hand on her shoulder with the suggestion of sunlight behind her and clouds in front of and below her. On the 2008 stamp, she was facing left; the artwork for this stamp shows her facing right to help differentiate between the two stamps.

President Ronald Reagan designated November as National Alzheimer’s Disease Awareness Month in 1983. At the time, fewer than 2 million Americans were diagnosed with Alzheimer’s; today, that number has soared to nearly 5.4 million.

The first-day event will be free admission and open to the public, though an RSVP is required to attend the ceremony. Those interested can RSVP at usps.com/alzheimers.

Postmaster General and Chief Executive Officer Megan J. Brennan will dedicate the stamp. In attendance will be Kathy Siggins of Mount Airy, Maryland, who followed the discretionary semipostal program criteria for submitting the stamp suggestion. Siggins’ husband succumbed to the disease in 1999.

Customers may pre-order the stamps atusps.com/shopin early November for delivery shortly after the Nov. 30 issuance.

The U.S. Postal Service has issued four previous semipostals, starting with the Breast Cancer Research in 1998, which was reissued in 2014. Subsequent semipostals have been the Heroes of 2001 (2002), Stop Family Violence (2003) and Save Vanishing Species (2011).

The Semipostal Authorization Act grants the U.S. Postal Service discretionary authority to issue and sell semipostal fundraising stamps to advance such causes as it considers to be ‘‘in the national public interest and appropriate.’’ Under the program, the Postal Service intends to issue five semipostal fundraising stamps over a 10-year period, with each stamp to be sold for no more than two years.

The Alzheimer’s semipostal stamp will be followed by a Post-Traumatic Stress Disorder (PTSD) semipostal in 2019. The next three discretionary semipostal stamps have not yet been determined.

Under the Act, the Postal Service will consider proposals for future semipostals until May 20, 2023.
